Description

It'd be great to have API docs for component testing. I could look into this if you could provide some pointers on where to place it?

@sand4rt For now, we can put more content into https://playwright.dev/docs/test-components. You can add a section describing the API. Once we are ready to go out of experiment, we'll figure out the right structure for docs.
